That doesn't make any sense. Javascript libs are just as blocking as any python or ruby lib.
"no big existing libraries of blocking code" (for js) just translates to "no big existing libraries", period.
It's not like javascript has any special support for non blocking code --or that any code that does anything useful and specific (ie. not just handling out work to be done and callback/returned but actually doing the work) can ever be non blocking.
